Solar energy systems generate electricity during daylight hours, but energy demand continues around the clock. This is where energy storage technologies come in—storing excess energy produced during the day and making it available when needed. Thanks to storage, solar power can be part of our lives not only during the day, but 24/7.
When it comes to energy storage today, the most widely used technology is lithium-ion batteries, which stand out with their high energy density, long cycle life, and low maintenance needs. Despite their compact size, these batteries offer high capacity and can operate integrated with smart energy management systems. Lead-acid batteries, which are more economical but have a shorter lifespan and lower efficiency, are still preferred for small-scale projects. In large-scale energy storage projects, flow batteries attract attention with flexible capacity options and long service life.
Modern energy storage systems don’t just store electricity—they also analyze production and consumption data to optimize performance automatically. For example, they can draw energy from the grid and store it during low-price hours, then use that stored energy when prices rise to reduce costs. At Zes Solar, we develop energy storage solutions tailored to projects of different scales, helping you achieve true energy independence by carrying clean solar energy into the night.
